Black Superman by Patrick D Cooper

More than ten years in the research and writing,
Black Superman addresses one of the most controversial debates in recent
American history: Why are African Americans and other people of African descent
so disproportionately represented among the greatest athletes in the world? And
what are the implications if African American athletic superiority is based on
genetic differences between them and other racial groups? In a persuasive and
engaging mix of sports, science, and history, Black Superman argues that the
athletic superiority of people of West African descent, in athletic activities
involving speed and power, is based on biologically-inconsequential,
environmentally-determined biochemical and biomechanical differences between
them and all other racial groups and on biochemical differences between them
and all other African populations.
